PAPER-CUTTING MECHANISM.

Application filed June 30,

To all whom it may concern:

Be it known that I, ADIN W. HrLsINenR, a citizen of the United States, residing at Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Paper-Cutting Mechanism, of which the following is a specification, reference being bad therein to the accompanying drawing.

My invention relates to improvements in box making machines and has particular reference to and is illustrated in the accompanying drawings in its application to a web or paper feeding mechanism for passing a sheet of material through the machine as the boxes or trays are cut and formed therefrom. The particular part of the machine to which this. invention relates re ceives the sheet or web from a feeding device, the same passing intermittently or in periodic: steps to the cutting mechanism, from which the cutoff pieces are periodically fed through the machine for further operations.

In the accompanying drawing, I have illustrated in 1 in perspective, parts being broken away, feeding and cutting mechanism, embodying an application of my invention. Fig. 2 is a perspective View of the knife and its support in inverted position. Fig.3 is a perspective view of the knife and bedplate of the cutting-off mechanism, Fig. 4 is a cross-section on the line 44 of Fig. 2, and Fig. 5 is an enlarged view of an adjustable bracket. shaft holder.

5 indicates the frame of the machine suitably braced as indicated at 6 and provided with a shaft 7 upon which is mounted the pulleys 8-8 which are beneath the pulleys S)9 upon the shaft 10, said shaft resting idly in the bearings 11-11 so that as the sheet feeds between the rollers 8-9 there is only frictional contact thereon, the rollers 88 rotating continuously. The shaft 7 is provided with a pinion 12 meshing with the pinion 13 which in turn meshes with the pinion 14 driven by the pinion 15 from the main drive of the machine, and upon the shaft 7 is also mounted the sprocket wheel 16 carrying the chain 17 which drives the sprocket 18 upon the shaft 19 carrying the pulleys 20-20 which are also thereby continuously rotated.

21 indicates shaft another normally 1922. Serial No. 572,094.

raised by springs such as 22-22 said shaft 21 carrying pulleys 23-23 which by virtue of the action of the springs 2222 are maintained out of contact with the pulleys 2020, but hooks 2424 are hung upon the shaft 21 and are at their lower extremity pivotally mounted upon the shaft 25 which in turn is pivotally secured in the rods 2626 secured upon the shaft 27 which shaft is provided with the lever 28 having a roller at one end 29 bearing upon the cam 30 on the shaft 31, so that periodically the rollers 23--23 are brought down in contact with the rollers 2020 gripping the sheet therebetween and periodically feeding the same leftwardly as pieces of the sheet are out by the cutter.

The cutter consists of tWobase plates 3233, separated sufficiently to permit the passage of the knife 34 retained in the upper plate 35, the same being shown in inverted position to better advantage in Fig.

2 where it will be seen that the knife 34 is higher at the centre than at the extremity, and is also pointed at the centre, thereby providing a shearing out instead of a. punch or straight out, and it will also be observed by reference to Fig. 4 that the cutting edge of the knife is concave as indicated at 36 instead of convex as usual. 37'37 indicate suitable clamps or plates for retaining the knife in position.

The face plates 3233 are rigidly secured upon the machine and the knife portion is raised and lowered in the yoke 38 adapted to reciprocate vertically in the guides 3939 by virtue of levers such as 40 pivotally secured at the ends of the yoke 38 and eccentrically mounted upon the shaft 31, from which it will be seen that as the card is fed periodically to the knife, the knife descends while the card is stationary, cutting off a predetermined length and as the stroke of the knife is completed, the rollers 2323 descend upon the card taking each cut-off piece successively from the knife. The continuous rotation of the rolls 88 does not feed the card continuously as the card is fed to the rolls intermittently and is not gripped by the rolls sufficiently thus the feed is intermittent. The operation of the knife is during the stationary period of'the intermittent feed.

Of course it Will be understood that various modifications may be made in the construction and arrangement of parts Without departing from the spirit of the invention as claimed.

I claim:

1. In a discharge mechanism of the class described, discharge rolls normally separated by a spring and means for bringing them together upon a blank to be discharged at predetermined intervals.

2, In a discharge mechanism of the class described,' discharge rolls normally separated by a spring and means for bringing them together upon a blank to be discharged at predetermined intervals, said means comprising hooks upon the axis of said rolls and means for actuating said hooks.

In testimony whereof I hereunto aflix my signature.
